Be it known that I, SAMUEL E. BEELER, a United States, residing atlfaynesboro, inthe county of Franklin and State of Pennsylvania, haveinvented certain new and useful Improvements in Steamngine Reverse, ofwhich the following is a specification.

My said invention provements in the consists in various vimtion for wearbetween all the vided so that the mechanism will at all times run trueand steady but at the same time freefrom binding' or undue friction, allas will be hereinafter more fully described and claimed.

In said drawings the portions marked A represent the crank-shaft and Bthe reverse disk. Said crank-shaft is, or may be, a

shaft A and formed with their outer tapered correspondingly to the taperrecess in the eccentric 2 and adapted to fit therein. Said gibs areconnected to a sliding sleeve 7, gib 3 by an adjusting bolt 5 and gib 1by a machine bolt 6. Ashifting yoke 13 is mounted on the sliding'sleeve7 between a fla-nge formed on one edges of the f yoke 13. By tiis meansthe nut 8 degree desired for securing a close working fit between theflange of sleeve 7 and the washer 10 and be then locked in suchposition, thus providing means to readily take up any wear between theparts and insure a close adjustment at all times.

2 is taken up by adjusting gib 3 through the medium of the adjustingstud, or bolt, 5,

which is connected to a flange of sleeve 7 by engages the radial pins 18operating' the said sliding sleeve.

As will be readily understood, the position of eccentric 2 on disk B isdetermined by the gibs 3 and 4 and may be changed from any positionbetween that shown in Fig. 3 to that shown in Fig. said gibs, asindicated, through the medium of lever 16. When the eccentric is in theextreme position shown in Fig. 3, the steam valve will have the properlead and motion he proper lead and motion for running the engine in theopposite direction. Less travel of the as may mined, to secure thedesired result.

djustment to compensate for wear between eccentric 2 and guides Z) isprovided by means of liners 17 mounted beneath said guides. It will benoted by reference to Fig. 2 that there is sufficient clearance betweenthe outer face of si de thereof the guides Z) and the secure by `LettersPatent,
